目的 :研究运动致疲劳后对肺通气功能产生的影响。方法 :采用实验法设计运动致疲劳方案,对比分析疲劳前后受试者肺通气功能变化。实验中首先在保证受试者在无疲劳状态的情况下进行肺通气功能测试;然后让受试者进行羽毛球训练课致疲劳之后,立即对其肺通气功能再次进行测试,利用Spss19.0统计分析软件对实验数据进行处理分析。结果 :通过对疲劳前和疲劳后的2次肺通气功能的测试结果对比分析,发现羽毛球运动致疲劳后用力肺活量(FVC)降低,由疲劳前的4.77±1.19L降低为4.31±1.16L;最大通气量(MVV)降低,由疲劳前的152.04±34.40L/min降低为137.04±28.64 L/min;用力呼吸时间(FET)降低,由疲劳前的3.89±2.75s降低为1.99±1.86s;1s钟肺活量(FEV1)升高,由疲劳前的4.33±0.94L降低为3.92±0.87L;最大呼吸流速(PEF)升高,由疲劳前的7.74±2.13L/s升高为9.41±1.40L/s。结论 :运动疲劳对肺通气功能具有显著的影响。
OBJECTIVE: To study the effects of exercise-induced fatigue on pulmonary ventilation. Methods: The experimental design of exercise-induced fatigue program, comparative analysis of lung function changes before and after fatigue in subjects. In the experiment, firstly, the lung function test was conducted to ensure that the subjects had no fatigue state; then, the subjects were tested for fatigue of the badminton training immediately after the lung ventilation function was tested again. Using Spss19.0 statistical analysis Software to deal with the experimental data analysis. Results: Comparing and analyzing the test results of the second pulmonary ventilation before and after fatigue, we found that the forced vital capacity (FVC) after fatigue caused by badminton decreased from 4.77 ± 1.19L before fatigue to 4.31 ± 1.16L; (MVV) decreased from 152.04 ± 34.40 L / min before fatigue to 137.04 ± 28.64 L / min, forced breath time (FET) decreased from 3.89 ± 2.75s before fatigue to 1.99 ± 1.86s, while 1s The heart rate (FEV1) increased from 4.33 ± 0.94L before fatigue to 3.92 ± 0.87L, and the maximum respiratory flow (PEF) increased from 7.74 ± 2.13L / s before fatigue to 9.41 ± 1.40L / s. Conclusion: Exercise fatigue has a significant effect on pulmonary ventilation.
